Question

I wanna read in a bitmap that I have in my drawable folder and store it as a Bitmap variable so that I can set it as a background. Would the best way to do this be using a “file reader”? like

  Bitmap decodeFile (String pathName) method

Or is there a way to just set it like this:

  Bitmap bmp = R.drawable."bitmapFileName"; 

(I have tried this but returns an int, just wondering if I was on the right track)

Any help would be great 🙂

Answer 1

The R.drawable."bitmapFileName" is, indeed, just an integer, for it is an index (static integer) at your project’s R class (see more here). You can load your bitmap from the resources’s folder like this:

Bitmap image = BitmapFactory.decodeResource(getResources(), R.drawable.yourBitmap);

I found this code at the Android Development Community.
